10 because 45x3=135 205-125=70 70 divided by 7 equals 10
Answer:
O-2(x+5)
Step-by-step explanation:
I have to much time on my hands
The answer would be 72 degrees because it rose 15 from the begining
4c + 36 because you have to multiple 4 x c which is 4c and then you have to multiply 4 by 9 which gives 4c + 36 (hope this helps)
Let the number of islands visited be x and that peninsulas be y
thus,
x+y=19
⇒y=19-x.........i
if he skydives twice in islands and thrice in peninsulas, then the total number of skydives will be:
2x+3y=45.....ii
substituting i in ii we get:
2x+3(19-x)=45
2x+57-3x=45
putting like terms together we get:
2x-3x=45-57
-x=-12
therefore
x=12
and
y=19-x=19-12=7
hence the number of islands visited was 12 and that of peninsulas was 7
